Question on these fuzes ... I have a document that tells me the difference between the MK 1, 2, and 3 ... I have a MK 4 and am working on a EOD p[ublication on these. What is the difference with the MK 4 version.

Also can people post pictures of the MK 1, 2, and 3 versions for a publication?

I am also looking for the dimentions of the fuzes. Diameter, total length and exposed length, and is there a difference between the 4 versions?

Thanks,

Joe
 
Hello Joe,

The Textbook of Ammunition 1936 gives an explanation of the differences among the MK 1, 2 and 3.
Hope this can help you.

Stef,

I have the differences between them, I was wondering what is different with the 4? All I have on the 4 is a picture of it.

Bloome,

Thanks ... thats what we have pictures of too ... could you give me the measurements off yours? Somehow we didn't get the measurements off the fuze when we had the chance.

Thanks,

Joe
 
Isn't the no221 similar to the 199? Because I do have a 221 in my collection ready to be measured if need be!
 
The Mark III fuze differs from the Mark IV in the top ring having no retaining, or postioning slot.

The Mark 5 fuze differs from the Mark 4 by having a body made of steel instead of metal.
The Mark 6 fuze differs from the Mark 4 in having a stepped shoulder.
The Mark 7 differs from the Mark 4 by having a stepped shoulder and a steel body.
The Mark 8 differs from the Mark 4 principally in having the body, cap and base plug made of zinc alloy.
The Mark 9 is generally similar to the mark 8, differing principally in having a brass body with stepped shoulder and circular escape holes.

Quatermass,

Do you have a scanned version of this manual you can post?

Handbook for the Ordnance, Q.F. 3.7-Inch, Marks 1, 2 and 3. 1945.

I would be interested in reading it.
